Best place to live close to Valencia Harbour

I am about to move to Valencia and I will be working at the harbour.I am not sure where to live.I do not have a car. My budget is limited so I am looking for a flatshare.I would like to live close to the harbour (easy to reach by bike/tram/bus/metro). I also would like to be able to go to the city and to the beach easily.I am looking for a relatively quiet place but close to a gym and groceries. I am told that the area near the harbour is dodgy. Is it really the case? Everywhere?Cabanyal for instance is a perfect location (close to the harbour, the beach and the metro) but I am told it is dodgy. And it is probably not the good moment to live there as the restoration of the area should start in September (?)
